Hi,
I derived a form that has a menu strip. I set the Modifiers option to Protected and also tried Public on the base form, but the menu strip remains locked after you inherited the form. How do I unlock the menu strip on the derived form

Anyone can help me on this Or is this a bug
If I'm correct. VS can only modify the form that is currently open. So if your form inherit from an other form it cannot change the parent one when you are in the child one. The only way to change it is through the code.
Hi,
This behaviour is by design and is sometimes referred to as Visual Inheritance lockdown "feature"... You'll have to manipulate MenuStrip's properties manually in the code.

How Do you a have sample code to be able to add more menu items on the menu strip that is locked
Thanks
Put the following code in your inherited form's constructor (after InitializeComponent line):
ToolStripMenuItem item = new ToolStripMenuItem("&Menu 1");
item.DropDownItems.Add("&Item 1");
item.DropDownItems.Add("&Item 2");
baseMenuStrip.Items.Add(item);
[baseMenuStrip is original MenuStrip control on the base form]

Andrej,
It appears that the menu item got added on the menu strip during debug mode,
but when I actually run my application, the item does not show up.
Andrej
After I added the code under the Initial Component, the menu item appears on the derived menu strip, however, when I click on Start Debugging, the menu item does not show up.
Don't edit the Visual Studio generated code, it probably erased any changes you made which it will sometimes do. Add extra menu items in the form constructor after the InitializeComponents call.
Personally, I like to add a context menu to my form and use that for visual design. Then in the constructor I just make it merge the items from my context menu into the main menu.
...and make sure you're instantiating and showing the derived form, not the base one... I've seen this one a couple of times...
Andrej
Why do I have to add the item on the base menu strip and not the derived form as is indicated on your code
You should put the above code in your derived form's constructor, adding additional items to the menu strip, declared on your base form [where you set its Modifier property to Protected].
Meaning - in your derived form, you're accessing and modifying the menu strip control, inherited from the base form, where it's originaly declared.

I see. Now I know what my problem is. I am accessing this form from another inherited form called LoginForm. LoginForm calls this form, but since they both are located in the same class Library I am referencing, LoginForm invokes the original form. How do I call the derived form instead of the original form if anyone can use a different for it The login form has the code to open the original form. Can I add the derived form name in the app.config and refer to that in the base LoginForm But how do I create an instance of that form from the base LoginForm
Thanks
I guess, what I like to do is extract the name of the Form from the app.config file and convert it to a Form Object and instantiate it within my code. Do you have a code that does similar to this that you can give me
Thanks
